About sunfile
sunfile is a product of New Harmonics LLC, a small studio in Seattle. It was built by one person who watched too many friends spend their evenings filling in the same forms by hand.
The wedge is the forms library. Once you have a clean per-municipality and per-utility template database, the work of each new install collapses from hours to seconds. Adding a new jurisdiction is a couple of hours of work, once, and then it renders forever.
Coverage is NJ + WA at launch. If your state is not in there yet, email and ask. If we get three installers asking for the same state we add it that week.
